Alstroemeria plant named ‘Staprisusa’

ABSTRACT

A new and distinct cultivar of Alstroemeria plant named ‘Staprisusa’, characterized by its compact and uniform plant growth habit; freely branching habit; freely flowering habit; and white, pink and yellow-colored flowers with dark purple-colored spots and stripes.

CROSS REFERENCE TO RELATED APPLICATIONS

The present application is related to copending U.S. Plant patent application Ser. No. 10/200,305.

Botanical classification cultivar designation: Alstroemeria hybrida cultivar Staprisusa.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Alstroemeria plant, botanically known as Alstroemeria hybrida, commercially used as a flowering potted Alstroemeria, and hereinafter referred to by the name ‘Staprisusa’.

The new Alstroemeria is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the breeding program was to develop new flowering potted Alstroemeria cultivars with compact and uniform plant growth habit and attractive flower colors.

The new Alstroemeria originated from a cross made by the Inventor in April, 1994 in Aalsmeer, The Netherlands, of a proprietary Alstroemeria hybrida selection identified as 93D834-16, not patented, as the female, or seed, parent with a proprietary Alstroemeria hybrida selection identified as 93G112-2, not patented, as the male, or pollen, parent. The new Alstroemeria was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross in a controlled environment in Aalsmeer, The Netherlands in June, 1995. The selection of this new Alstroemeria was based on its compact plant growth habit and attractive flower coloration.

Asexual reproduction of the new cultivar by root divisions taken in a controlled environment in Aalsmeer, The Netherlands, since June, 1995, has shown that the unique features of this new Alstroemeria are stable and reproduced true to type in successive generations of asexual propagation.

SUMMARY OF THE INVENTION

Plants of the cultivar Staprisusa have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Staprisusa’. These characteristics in combination distinguish ‘Staprisusa’ as a new and distinct cultivar:

1. Compact and uniform plant growth habit.

2. Freely branching habit, bushy appearance.

3. Freely flowering habit.

4. White, pink and yellow-colored flowers with dark purple-colored spots and stripes.

Plants of the new Alstroemeria are most similar to plants of the parent selections. However, plants of the new Alstroemeria differ from plants of the parents in flower coloration as plants of the female parent have purple-colored flowers and plants of the male parent have yellow-colored flowers. In addition, plants of the new Alstroemeria are more compact than plants of the male parent.

Plants of the new Alstroemeria differ from plants of the cultivar Staprisara, disclosed in U.S. Plant patent application Ser. No. 10/200,305, primarily in flower coloration.

Plants of the new Alstroemeria can be compared to plants of the cultivar Staprilene, disclosed in U.S. Plant Pat. No. 11,683. In side-by-side comparisons conducted in Rijsenhout, The Netherlands, plants of the new Alstroemeria differed primarily from plants of the cultivar Staprilene in flower coloration as plants of the cultivar Staprilene had white-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Alstroemeria, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Alstroemeria. The photograph comprises a side perspective view of a typical flowering plant of ‘Staprisusa’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph, following observations and measurements describe plants of the new Alstroemeria grown in Rijsenhout, The Netherlands in a glass-covered greenhouse in 17-cm containers. During the production of the plants, day temperatures ranged from 15 to 25° C. and night temperatures ranged from 10 to 15° C. Plants used for the photograph and description were about four months from planting root divisions. The photograph and the description were taken during August and September, 2001.
